Let me jump in here.
Your car is responding exactly the way it was designed to. It was programmed to come on at 230 without A/C
Here is a description of the circuit from the service manual
ELECTRIC ENGINE COOLING FAN AND RELAY
These vehicles use 2,360 mm (14.2 inch) cooling fans to aid air flow through the radiator. Electric motors drive the cooling fans. These motors are attached to the radiator. Motor size varies with each engine option.
A coolant temperature switch activates the fan motors. This switch regulates voltage to the cooling fan relay. This switch operates the fan whenever the engine coolant temperature exceeds 11O C (230 F). For location and diagnosis, refer to Diagrams. A transducer can also activate the circuit, depending on the A/C compressor head pressure going to the condenser.
The engine cooling fan relays provide the high current required for the cooling fan motors using a low current signal coming from the Powertrain Control Module (PCM). This signal is a function of various inputs.
Refer to Diagrams for further information and diagnosis of the cooling fan relay.
